Vab XX hermaphrodites and XO males, viable at all temperatures. Adult hermaphrodite tail spike is invariably shortened and/or vacuolated, often also abnormal in larvae. Possible excretory cell abnormalities. Rays of adult male tail variably abnormal, other structures normal; males can mate.

Unable to propagate indefinitely: lines become sterile from F10-F28, with short telomeres and fused chromosomes. Hypersensitive to X-irradiation; weak Him phenotype; strong Him phenotype in later generations resulting from X-A fusions. Cross once or twice, freeze down many F2 mrt-2 plates, and go back to these plates every two months for fresh a mrt-2 line. A BstN1 RFLP makes the mrt-2 mutation easy to track.
